Elastic fabric with sinusoidally disposed wires

Abstract

A fabric for use with a system for monitoring prescribed body functions comprising an elastic fabric, adapted to be carried by a torso, which is stretchable in its longitudinal direction so as to expand and contract in response to body movement and size. The carrier includes at least one conductive and inelastic yarn arranged longitudinally of and located between upper and lower surfaces. The conductive yarn is arranged in sinusoidal configurations longitudinally of the fabric. The conductive yarn forms a breakout through one of the outer surfaces, at selected locations along the length of the fabric, forming opposed exposed ends above the surface. A monitoring unit, which includes a connector and a sensor, is secured with the one surface at the breakout with the connector being united with the exposed ends of the conductive yarn. The fabric acts to maintain the monitoring unit in a desired stationary position allowing the sensor to sense signals emitted from the torso and transmit these senses signals.

Description

CROSS REFERENCE TO RELATED APPLICATION [0001] This application claims priority from a provisional application filed Dec. 13, 2004, under Application Ser. No. 60 / 635,496 having the same title.BACKGROUND OF THE INVENTION [0002] The present invention is directed to woven elastic fabrics which include one or more conductive wires and which are designed to carry systems which monitor selected prescribed body functions. [0003] Elastic fabrics designated to carry monitoring devices are known in the art, as illustrated by U.S. Pat. No. 6,551,252. In this patent, there is only one disclosed fabric, i.e. a warp knitted fabric. The patent states that any of all fabric forming modes may be utilized, however, only one is described. [0004] The primary drawback to a knit fabric, as above referred to, is that the conductive yarns can be controlled to lie in only a single fabric plane. [0005] In fabrics used for carrying and positioning body function monitoring equipment it is most desirable and acc...

AI Technical Summary

Benefits of technology

[0021] There are also provided elastic stuffer yarns which extend longitudinally of the fabric, within each of the cells, on opposite sides of each of the conductive yarns. The stuffer yarns act to stabilize the conductive yarns within the cells.

[0026] (D) Causing the elongated elastic warp yarns to contract reducing the fabric length, causing the sinusoidal configurations to assume enlarged sinusoidal shapes between the upper and lower surfaces while the upper and lower surfaces formed of the elastic warp yarns maintain the controlled sinusoidal shapes and the conductive warp yarns to remain within the cells.

Problems solved by technology

The primary drawback to a knit fabric, as above referred to, is that the conductive yarns can be controlled to lie in only a single fabric plane.
